Why WetlandDesigner

Nature Does It Better & Cheaper

Constructed wetlands cost 50-70% less than conventional STPs to build and 80-90% less to operate. For decentralised wastewater treatment, nature-based solutions are unmatched.

🌱
4 System Types
Horizontal flow CW, vertical flow CW, waste stabilization ponds, and duckweed-based systems — each with engineering-grade sizing using established design equations.
💰
Cost Comparison
CAPEX and annual OPEX estimates for each system using Indian construction rates. Compare nature-based vs conventional (SBR, MBR, MBBR) side by side.
📜
CPCB Standards
Designs target CPCB discharge standards (inland, public sewer, irrigation), NGT 2019 STP standards, NMCG Ganga norms, and SBM 2.0 requirements.
Need Detailed Engineering Design?

Our water team has IIT Bombay research heritage in nature-based treatment. We design constructed wetlands, WSPs, and hybrid systems from feasibility through DPR to construction supervision.

Constructed Wetlands for Wastewater Treatment in India

The NGT 2019 Order mandated STPs for all towns above 10,000 population. NMCG promotes constructed wetlands as cost-effective alternatives to conventional STPs for small towns. WetlandDesigner sizes systems based on CPCB discharge standards (EPA 1986), NGT effluent limits (BOD < 10 mg/L, TSS < 20 mg/L), and WHO 2006 guidelines for wastewater reuse.

SBM 2.0 Applications

Swachh Bharat Mission 2.0 (Urban) promotes decentralised wastewater treatment including constructed wetlands for greywater management. WetlandDesigner helps municipalities design systems meeting SBM 2.0 specifications.
